Possibly as part of the whole Ovi server shake-up, possibly as part of the new Ovi Maps server architecture, Nokia's Maps servers have now been 'fixed' and will, after a frustrating couple of months of being broken, successfully match full seven character UK postcodes. Phew - just thought you'd like to know. 

You can find Nokia Maps on your device, in Download!, or via maps.nokia.com in Web.

Thanks to Imran for the heads-up.
